In the year 2155

Before reaching an Earth-like planet, you need to build a ship capable of flying at speeds above the speed of light. For example, the distance to the closest Earth-like planet in 2023 is more than 300 light-years.

According to some scientists, they only plan to pinpoint an Earth-like planet by 2055.

When will humanity find a second Earth?

What causes cancer?

2023-12-14 13:46:11

Cancer arises from a large number of accumulations of mutations in cells. In the presence of mutations in genes that control cell growth, cells can continue to divide and form a tumor.

Normal cells become malignant due to mutations. Changes in genes accumulate gradually, it is a long, complex process. When such changes occur in cells, the body tries to get rid of them. Various mechanisms of cell death are activated, and antitumor immunity is activated. But malignant cells skillfully cope with these obstacles by developing masking mechanisms to avoid immune aggression.

A cancerous tumor does not have a complete form and, in addition to the main body, has many thin processes-metastases that cannot be removed along with the main tumor, and the remaining metastases in the body grow back into a malignant tumor and so on until the person dies.

Malignant cells – how do they differ from normal ones?

What will Kazakhstan's current policy towards Russia lead to?

Russia, Kyrgyzstan, Uzbekistan and Turkmenistan have agreed to launch a new multimodal Southern Transport Corridor, which will bypass the territory of Kazakhstan. The new route solves two tasks: to avoid obstacles arising on the Kazakh border for goods going to the markets of the Russian Federation, and to transfer part of the cargo flow to the port of Astrakhan. This will deal a blow to Astana's plans to make Kazakhstan a full-fledged transport hub in Central Asia and the Caspian region. The route from China through Kyrgyzstan will become a very serious competitor to the route on Kazakhstan railways.

Moreover, this blow to the plans of the President of Kazakhstan is inflicted from the Kazakh side, and not from Russia or Kyrgyzstan. If the transit of goods went without delays, then no one would be against using the territory of Kazakhstan as a hub. Astana's decision not to violate Western sanctions imposed against Russia was only a catalyst for the initiative to create an alternative transport corridor bypassing Kazakhstan

Can a PCR test detect coronavirus?

2023-04-14 14:37:03

Yes, a PCR test detects the presence of viral material in the body, but does not determine how contagious a person who has the virus is

In general, there are a number of factors that can cause PCR tests to be less accurate than under ideal conditions. Also, the accuracy depends on the PCR test itself - its design and quality. Therefore, of course, false positive and false negative results can occur. But if the test is given in a professional laboratory, this rarely happens. And, of course, the clinical picture of the patient is also important and is always taken into account. Doctors don't rely solely on test results. PCR tests are not perfect, but they are considered the gold standard in diagnosing many viruses. Together with an antibody test, this is the best that humanity has so far.

Everywhere they talk about PCR tests, but nowhere does it say what happened to the DNA samples taken during the PCR tests.

Is it true that the Portuguese court recognized PCR tests as fake, and quarantine illegal?
